I feel stupid, but I can't explain this.. I have a table with a cell (blob type). If I store a blob there with 885 bytes, it takes ~1,2ms (localhost) to request that partition. If it's 1794 bytes, it only takes 0,1ms. Both have single cell per partition.

it looks like ccm will grok an env for `CCM_CONFIG_DIR`, so I'm thinking that setting `CCM_CONFIG_DIR=$WORKSPACE/.ccm` might be a better idea, since it will automatically get cleaned up then started fresh each run

evidently, the slaves krut added have 40G disks, so there's little free space to work with - INFRA says /home/jenkins is ~15G, there are ~13G of dependencies + OS, so only about 7GB of workspace to use
